在生产实践中,我们多次发现雌鱼产卵后,雄鱼的精液仍很充沛。那么,能否以一条雄鱼配几条雌鱼呢?如果能成功,那就可以多养雌亲鱼,少养雄亲鱼,从而提高亲鱼塘的生产效率,节约成本。经多年试验证明,用一点五(雌)比一(雄)到四(雌)比二(雄),都可获得很高的受精率。一九八○年五月,我们在吉水县鱼种场催产四条 In production practice, we have found many times that the female’s semen is still abundant after spawning. So, with a male fish with a few female? If successful, then you can raise more female fish, less raised male fish, thereby enhancing the pro-fish pond production efficiency and cost savings. After many years of testing, it has been proven that high fertility rates can be achieved with one in five (female) to one (male) to four (female) to two (male). In May 1980, we staged four births in the fish farm of Jishui County
